Dude, with liver or chicken liver I rinse it under cold water, boil it for 15 minutes (just a slow boil and don’t let it boil over or you’ll be sorry LOL ) drain it and rinse again if it’s really scummy, let it cool, cut it into strips or if you’re really bored, bite sized pieces, then throw it on a baking sheet and put in oven at around 200f…..should take around 45 minutes to an hour…I like mine still a little spongy but see what the pups like
I don’t bother making the cake, liver’s dirt cheap anyway
it’s easy good luck
